Generally, the system dumps a large amount of data and requires platform-related tools to analyze, such as on Windows windbgand Linux gdb.
System dump : A dump of the local system generated by the JVM, also known as a core dump.The Java program triggers the dump operation by adding appropriate conditional parameters when starting the Java program. Dump : The performance analysis tool obtains the current state data from the memory and stores it in a file for static performance analysis.There are usually multiple views (View) that display CPU usage, memory usage, thread status, and other useful information in real time, so that users can quickly find the key to the problem. Monitoring : Monitoring is a general method used to view the runtime behavior of an application.background knowledge The main way of performance analysis In this article, we mainly introduce two performance analysis tools, VisualVM and JProfiler. In order to find these hidden problems in the program, performance analysis tools are often used to analyze and optimize the performance of the application in the later stage of the project development. As the application continues to run, it may cause the efficiency of the entire system to decrease, and in severe cases, it may cause the system to crash. In the process of developing large-scale Java applications, we will inevitably encounter problems such as memory leaks and performance bottlenecks, such as unreleased connections to files, networks, and databases, and unoptimized algorithms.
